Kernel Panic Mac OS verison: not yet set

[feluxz]

Hello, i have had a mountain lion install stable for over 2 years. Now i get a kernel panic at boot.
It says:
BSD process name corresponding to current thread: kernel_task
Boot args: boot-uuid=874D164E-E496-3344-B149-7A33D7B69129 rd=*uuid PCIRootUID=1 -f

Mac OS version:
Not yet set


Is it possible to fix this in some way? Unfortunately i don't have a back up. One thing to mention is that it is a "fusion drive"
If it's not possible to fix this how should i go about to get my files? Could i install Mac OS on another hard drive and get the files from there?

Thanks for answers!

Installed Mountain lion on a different HDD in the hopes to use the fusion drive (where my previous install is) as a storage HD and copy my old files to the new one. But one strange thing is that if i connect the fusion drive to the motherboard i get a kernel panic at boot even if i boot to my newly installed HDD. Any ideas?
